CROSS-REFERENCE TO RELATED U.S. APPLICATION

This application claims the benefit of, and priority to, U.S. Patent Application No. 62/200,963, filed Aug. 4, 2015, the disclosure of which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

This disclosure relates generally to multi-cell partitions for use in separating multiple items for storage and/or transport of the multiple items, and more specifically to such partitions that are collapsible for storage and/or transport thereof when not in use separating multiple items.

BACKGROUND

Some conventional multi-cell partitions for storing and/or transporting items are not readily collapsible between open and closed configurations thereof. While other conventional multi-cell partitions may be readily collapsible, such partitions typically require adhesive or other type of permanent bonding to form the collapsible structure. It is desirable to provide a multi-cell partition which is readily collapsible between open and closed positions and which does not require the use of adhesives or other bonding media in its construction.

DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

For the purposes of promoting an understanding of the principles of the invention, reference will now be made to a number of illustrative embodiments shown in the attached drawings and specific language will be used to describe the same.

Referring now to FIGS. 1-3B, various components are shown from which a multi-cell partition may be constructed. It will be understood that in FIGS. 1-3B, the structures and features illustrated in FIGS. 1A and 2 are scaled and aligned with each other, and that the structures and features illustrated in each of FIGS. 1A, 1B, 3A and 3B are likewise scaled and aligned with each other.

Referring specifically to FIGS. 1A and 1B, a planar support panel 12 illustratively forms a base or support to which one or more partition walls is/are mechanically attached, as will be described in detail below. The panel 12 defines a top surface 14 between opposing ends 16, 18 and between opposing sides 20, 22 which extend between the opposing ends 16, 18. The panel 12 illustratively defines a bottom surface 24, opposite the top surface 14, as illustrated in FIG. 4.

The panel 12 includes a plurality of fold lines which are illustratively pre-formed in and along the panel 12 using any conventional technique therefor. In the illustrated embodiment, the panel 12 includes three such fold lines 26, 28A and 28B. The fold line 26 extends between the opposing ends 16, 18, and divides the top surface 14 of the panel 12 into one surface portion 14A extending between the side 20 and the fold line 26 and another surface portion 14B extending between the side 22 and the fold line 26. In the illustrated embodiment, the fold line 26 is parallel with the opposing sides 20, 22 and perpendicular to the opposing ends 16, 18. In some alternate embodiments, the fold line 26 may be non-parallel with the opposing sides 20, 22 and/or may be non-perpendicular with the opposing ends 16, 18. In the embodiment illustrated in FIG. 1A, the fold line 26 is positioned equidistant from each of the opposing ends 16, 18 such that the fold line 26 bisects the panel 12 in a direction parallel with the opposing sides 20, 22 and the fold line 26 divides the top surface 14 into halves 14A, 14B. In some alternate embodiments, the fold line 26 may be alternatively positioned, e.g., closer to one or the other of the opposing sides 16, 18.

The fold lines 28A, 28B each also extend between the opposing ends 16, 18, and in the illustrated embodiment the fold lines 28A, 28B are both parallel with and spaced apart from respective ones of the opposing sides 20, 22 (and perpendicular to the opposing ends 16, 18). In some alternate embodiments, the fold line 28A and/or the fold line 28B may be non-parallel with the respective one(s) of the opposing sides 20, 22 and/or may be non-perpendicular with the opposing ends 16, 18. In the embodiment illustrated in FIG. 1A, the fold line 28A is spaced apart from the side 20 of the panel 12 to form a flap or tab 32 therebetween, and the fold line 28B is spaced apart from the side 22 of the panel 12 to likewise form a flap or tab 34 therebetween, and the flaps or tabs 32, 34 each extend between the ends 16, 18 of the panel 12. The surface portion 14A that extends over the flap or tab 32 defines a top surface 32A of the flap or tab 32, and the surface portion 14B that extends over the flap or tab 34 defines a top surface 34A of the flap or tab 34. As illustrated in FIG. 1A, the top surfaces 32A, 34A of the flaps or tabs 32, 34 respectively are co-planar with the portions 14A, 14B respectively of the top surface 14 of the panel 12 when the fold lines 28A, 28B are fully unfolded. As further illustrated in FIG. 1B, each of the flap or tab 32, 34 forms an upstanding exterior side wall 32, 34 when the fold lines 28A, 28B are fully folded, such that the exterior side wall 32 extends upwardly, and illustratively perpendicularly, away from the top surface 14 between the fold line 28A and the end 20 of the panel 12, and the exterior side wall 34 likewise extends upwardly, and illustratively perpendicularly, away from the top surface 14 of the panel 12 between the fold line 28B and the end 20 of the panel 12, and such that the top surfaces 32A, 34A of the upstanding exterior side walls 32, 34 face each other. With the fold lines 28A, 28B in their fully folded states, as illustrated in FIG. 1B, the upstanding exterior side walls 32, 34 illustratively define terminal side walls of the panel 12.

In the embodiment illustrated in FIG. 1A, a number of slots are formed in and through the panel 12 along the opposing sides 16, 18. In the illustrated embodiment, six such slots 30A₁-30A₆ are formed through and along the side 20 of the panel 12, i.e., through the flap or tab 32, and are spaced apart along the side 20 between a first slot 30A₁ adjacent to the end 16 of the panel 12 and a sixth slot 30A₆ adjacent to the opposite end 18 of the panel 12. Six corresponding slots 30B₁-30B₆ are formed through and along the side 22 of the panel, i.e., through the flap or tab 34, and spaced apart along the side 22 between a first slot 30B₁ adjacent to the end 16 of the panel 12 and a sixth slot 30B₆ adjacent to the opposite end of the panel 12. Illustratively, each of the slots 30A₁-30A₆ is axially aligned with a corresponding one of the slots 30B₁-30B₆ to form a number of aligned pairs of slots 30A₁/30B₁, 30A₂/30B₂, etc. Each slot 30A₁-30A₆ extends from the side 20 toward the fold line 28A, and illustratively terminates short of the fold line 28A. Each slot 30B₁-30B₆ likewise extends from the opposite side 22 toward the fold line 28B, and illustratively terminates short of the fold line 28B. In alternate embodiments, one or more of the slots 30A₁-30A₆ may extend to or through the fold line 28A, and/or one or more of the slots 30B₁-30B₆ may extend to or through the fold like 28B. In any case, each axially aligned pair of slots 30A₁-30A₆ and 30B₁-30B₆ is configured to engage corresponding slots formed in each of a corresponding set of elongated cross walls as will be described below with respect to FIGS. 3A and 3B.

Referring now to FIG. 2, an embodiment is shown of a an interior side wall 40 having a bottom end 42 and a top end 44 each extending between opposing ends 46 and 48 of the interior side wall 40. Any number of interior side walls 40 may be positioned along the top surface 14 of the planar panel 12 between the opposing ends 14, 16. In the illustrated embodiment, any such number of interior side walls 40 will extend along the top surface 14 of the panel 12 generally parallel with the fold lines 26, 28A, 28B, and therefore parallel with the exterior side walls 32, 34 when the fold lines 28A, 28B are fully folded, and perpendicular to the planes defined by the opposing ends 16, 18 of the panel 12, with the bottom ends 42 thereof in contact with, and supported by, the top surface 14 of the panel 12 and the top end 44 extending away from the top surface 14 when the panel 12 is open with the upstanding side walls 32, 34 extending upwardly away from the top surface 14 of the panel 12 as illustrated in FIG. 1B.

A number of slots are formed in the top end 44 of the interior side wall 40, and in the illustrated embodiment six such slots 50 ₁-50 ₆ are spaced apart along the top end 44 of the interior side wall 40 between the opposing ends 46, 48. Each of the six slots 50 ₁-50 ₆ illustratively aligns axially with corresponding ones of the slots 30A₁-30A₆ and 30B₁-30B₆ when the interior side wall 40 is positioned on the surface 14 of the panel 12 with the panel 12 open and with the upstanding side walls 32, 34 extending upwardly away from the top surface 14 of the panel 12 as illustrated in FIG. 1B. In such embodiments, each axially aligned set of slots 30A₁-30A₆, 30B₁-30B₆ and 50 ₁-50 ₆ is configured to engage corresponding slots formed in each of a corresponding set of elongated cross walls as will be described below with respect to FIGS. 3A and 3B.

Referring now to FIGS. 3A and 3B, an embodiment is shown of a cross wall 60 having a bottom end 62 and a top end 64 each extending between opposing ends 66 and 68. Any number of cross walls 60 may be positioned along the top surface 14 of the planar panel 12 between the opposing sides 20, 22 (and/or between the upstanding side walls 32, 34) thereof. In the illustrated embodiment, any such number of cross walls 60 will extend along the top surface 14 of the panel 12 generally perpendicular with the fold lines 26, 28A, 28B and parallel to the planes defined by the opposing ends 16, 18 of the panel 12, with the bottom ends 62 thereof in contact with, and supported by, the top surface 14 of the panel 12 and with the top end 64 extending away from the top surface 14 when the panel 12 is open with the upstanding side walls 32, 34 extending upwardly away from the top surface 14 of the panel 12 as illustrated in FIG. 1B.

A number of slots are illustratively formed in the bottom end 62 of the cross wall 60, and in the illustrated embodiment seven such slots 70 ₁-70 ₇ are spaced apart along the bottom end 62 of the cross wall 60 between the opposing ends 66, 68 thereof. In the illustrated embodiment, the slot 70 ₁ adjacent to the end 66 of the cross wall 60 is configured to engage one of the slots 30A₁-30A₆ defined in the side 20 of the panel 12, and the slot 70 ₇ adjacent to the end 68 of the cross wall 60 is configured to engage a corresponding one of the slots 30B₁-30B₆ defined in the side 22 of the panel 12, and each of the five remaining slots 70 ₂-70 ₆ is configured to engage one of the slots 50 ₁-50 ₆ in each of five interior side walls 40 positioned on, and spaced apart across, the top surface 14 of the panel 12 with the panel 12 in its open position with the upwardly extending side walls 32, 34 extending upwardly away from the top surface 14 of the panel 12 as illustrated in FIG. 1B.

The cross wall 60 further includes a fold line 72 which illustratively extends between the top end 64 and the bottom end 62 thereof. In the illustrated embodiment, the fold line 72 is illustratively aligned with the slot 70 ₄ (i.e., centrally through the side wall 60 relative to the ends 66, 68) such that the fold line at least partially bisects the cross wall 60. In the embodiment illustrated in FIGS. 3A and 3B, the fold line 72 need not extend completely down to the bottom end 62 of the side wall 60 as the slot 70 ₄ with which it is axially aligned provides for complete folding of the cross wall 60 at the fold line 72. In other embodiments in which the fold line 72 is not aligned with a slot formed in the cross wall 60, the fold line 72 illustratively extends from the top end 64 to the bottom end 62 of the cross wall 60. In the illustrated embodiment, the fold line 72 is also illustratively aligned with the fold line 26 of the panel 12 when the cross wall 60 is coupled to the panel 12 as described above such that the side wall 60 and the panel 12 together fold along the fold lines 72, 26 respectively. In some alternate embodiments in which the fold line 26 of the panel 12 is positioned closer to either of the panel sides 20, 22, the fold line 72 may likewise instead be positioned closer to either of the ends 66, 68 in order to maintain alignment of the fold line 72 with the fold line 26. In other alternate embodiments, the fold line 72 may not be aligned with the fold line 26.

In the embodiment illustrated in FIGS. 1A-3B, the panel 12, interior side wall 40 and cross wall 60 are each configured such that the resulting constructed multi-cell partition includes six cross walls 60 and five interior side walls 40, with the cross walls 60 and the flaps or tabs 32, 34 defined at the sides 20, 22 respectively of the panel 12 coupled together as described above, and with the interior side walls 40 and the cross walls 60 coupled together as also described above. In some alternate embodiments, the resulting multi-cell partition may include more or fewer interior walls 40 and/or more or fewer cross walls 60, e.g., with a minimum of at least one cross wall 60 and no interior side walls 40, and with no maximum number of cross walls 60 or interior side walls 40. Alternatively or additionally, either or both of the slots adjacent to the ends 66, 68 of one or more cross walls 60 may be formed in the top 64 thereof, and in such embodiments either or both of the corresponding slots formed in the sides 20, 22 of the panel 12 may be alternatively formed in the panel 12 adjacent to the sides 20, 22, e.g., beginning at or near the fold line(s) 28A, 28B and extending toward but terminating short of the side 20, 22 of the panel 12. In any of the foregoing alternative embodiments, one or more interior side walls 40 and one or more cross walls 60 may be formed such that one or more of the cross wall engaging slots 50 ₁-50 ₆ is/are formed in the bottom surface 42 of the one or more interior side walls 40 and/or one or more of the interior side wall engaging slots 70 ₂-70 ₆ is/are formed in the top surface 64 of the one or more cross walls 60. In any such alternative embodiment(s), it will be understood that the resulting multi-cell partition may include as few as one cross wall 60 coupled between the opposing sides 20, 22 of the panel 12 and with no upper limit on the total number of cross walls 60, and/or may include as few as no interior side walls 40 and with no upper limit on the maximum number of interior side walls 40. One minimal configuration, for example, may include only a single cross wall 60 which is coupled adjacent each end 66, 68 thereof to a respective side 20, 22 of a panel 12, and which thus forms a 2-cell partition along the top surface 14 of the panel 12 with the panel 12 in its open position with the upwardly extending side walls 32, 34 extending upwardly away from the top surface 14 of the panel 12 as illustrated in FIG. 1B.

In still further alternate embodiments of the multi-cell partition, fewer than all of the total number of cross walls 60 may be coupled directly to the sides 20, 22 of the panel 12 as depicted in the embodiment illustrated in FIGS. 1A-3B. One such embodiment 80 is illustrated in FIGS. 4-6 which includes six cross walls but in which only two of the cross walls 60, e.g., the two cross walls 60 ₁ and 60 ₂ adjacent to the opposing ends 16, 18, respectively (see, e.g., FIGS. 5 and 6), are coupled directly to the sides 20, 22, e.g., to the flaps or tabs 32, 34, of the panel 12 as described above. The remaining four cross walls 60′ are illustratively identical to the cross walls 60 with the exception that their lengths extend only between the fold lines 28A, 28B of the panel 12′ and therefore do not couple directly to the sides 20, 22 of the panel 12′. Rather, the short ends of the cross walls 60′ abut or extend adjacent to or near the top surfaces 32A, 34A of the upstanding exterior side walls 32, 34 of the panel 12′ respectively when the panel 12′ is in its open configuration with the upstanding exterior side walls 32, 34 extending upwardly away from the top surface 14 of the panel 12 as illustrated in FIG. 1B. In this embodiment, the panel 12′ of the multi-cell partition 80 is also modified in that it includes only two slots per side, i.e., a slot 30A₁ defined into and through the side 20 near the end 16 of the panel 12′, a slot 30B₁ defined into and through the opposite side 22 near the end 16 and axially aligned with the slot 30A₁, a slot 30A₂ defined into and through the side 20 near the end 18 of the panel 12′ and a slot 30B₂ defined into and through the opposite side 22 near the end 18 and axially aligned with the slot 30A₂.

In the assembled multi-cell partition 80 illustrated in FIG. 4, the partition 80 is illustratively collapsed to a closed or storage position or state in which the planar panel 12′ is fully folded along the fold line 26 and fully unfolded along each of the fold lines 28A, 28B (only the fold line 28A is shown in FIG. 4), and in which each of the elongated cross walls 60, 60′ is fully folded along its fold line 72. In this closed position of the partition 80, the opposing sides 20, 22 of the panel 12′ are substantially juxtaposed with each other with a portion of the folded plurality of cross walls 60, 60′ and interior side walls 40 coupled thereto positioned between the folded surfaces 14A, 14B of the top surface 14 (only the top surface 14B shown in FIG. 4) of the folded panel 12′ and another portion of the folded plurality of cross walls 60, 60′ and interior side walls 40 coupled thereto extending outwardly from the folded panel 12′ away from the end 18 of the panel 12′. In this closed position, the opposing sides 20, 22 of the folded panel 12′ are illustratively separated only by the portion of the folded plurality of cross walls 60, 60′ and interior side walls 40 coupled thereto that is positioned between the folded surfaces 14A, 14B of the top surface 14 of the folded panel 12′. Illustratively, folding of the plurality of cross walls 60, 60′ along their fold lines 72 draws the exposed portion of the plurality of cross walls 60, 60′, and portions of the interior side walls 40 coupled thereto, outwardly from between the folded faces of the top surface 14 of the folded panel 12′, and this action illustratively also causes the fold lines 28A, 28B to fully unfold by forcing the flaps or tabs 32, 34 outwardly as illustrated in FIG. 4.

In FIG. 5, the partition 80 is shown partially unfolded, e.g., in the process of unfolding the panel 12′ from its fully stored position of FIG. 4 to its fully open position illustrated in FIG. 6, or in the process of folding the panel 12′ from its fully open position illustrated in FIG. 6 and its fully stored position of FIG. 4. In the former case, as the panel 12′ is being forced open, the fold line 26 and the fold lines 72 all transition from their fully folded position (e.g., illustrated in FIG. 4) to an unfolded position, and the action of unfolding the fold lines 72 causes the ends of the cross walls 60 engaging the panel 12′ (i.e., via engagement of the slots 70 ₁ with the slots 30A₁ and 30A₂ and engagement of the slots 70 ₇ with the slots 30B₁ and 30B₂) to draw the flaps or tabs 32, 34 toward their positions as upstanding side walls 32, 34.

In FIG. 6, the partition 80 is shown in its fully open position with the planar panel 12′ fully unfolded along the fold line 26 and fully folded along each of the fold lines 28A, 28B to form the pair of upstanding exterior side walls 32, 34, and with each of the elongated cross walls 60, 60′ fully unfolded along their fold lines 72. The bottom ends 62 of each of the cross walls 60, 60′ extend along, and are illustratively supported by, the planar top surface 14 of the panel 12′ between the upstanding exterior side walls 32, 34 (e.g., parallel to planes defined by the opposing ends 16, 18 of the panel 12′ and perpendicular to planes defined by the upstanding exterior side walls 3, 34 between the fold lines 28A, 28B and the panel ends 20, 22 respectively), and the bottom ends 42 of each of the interior side walls 40 extend along, and are illustratively supported by, the planar top surface 14 of the panel 12′ between the opposing ends 16, 18 thereof (e.g., parallel to the planes defined by the upstanding exterior side walls 32, 34 between the fold lines 28A, 28B and the panel ends 20, 22 respectively and perpendicular to the planes defined by the opposing ends 16, 18 of the panel 12′). Each slot 50 ₁-50 ₆ of each interior side wall 40 engages a corresponding slot 70 ₂-70 ₅ of a corresponding one of the cross walls 60, 60′ to form therebetween multiple cells of the multi-cell partition 80 between the upstanding side walls 32, 34 and between the opposing ends 16, 18.

As briefly described above, in some alternate embodiments either or both of the slots adjacent to or near the ends 66, 68 of one or more cross walls 60 may be alternatively formed in the top 64 thereof, and in such embodiments either or both of the corresponding slots formed in the sides 20, 22 of the panel 12 may be alternatively formed in the panel 12 spaced apart from the sides 20, 22, e.g., beginning at or near the fold line(s) 28A, 28B and extending toward but terminating short of the side 20, 22 of the panel 12. Referring to FIG. 7, such an embodiment 80′ of the multi-cell partition is shown which includes an alternate cross wall 60″ having slots 70 ₂ and 70 ₃ extending upwardly from the bottom end 62 of the cross wall 60″ as described above with respect to FIG. 3A, and in which the slot 70 ₁′ formed near the end 66 of the cross wall 60″ extends downwardly from the top end 64 toward the bottom end 62 thereof. The corresponding slot 30A2′ formed in the panel 12″ is illustratively spaced apart from the side 20, beginning at or near the fold line 28A and extending toward but terminating short of the side 20 of the panel 12″. In the illustrated embodiment, the slot 30A₂′ is augmented by an auxiliary slot, e.g., in the form of a horizontal slot 31 which extends from the end 18 of the panel 18 at or near the fold line 28A toward and intersecting the slot 30A₂′. In this embodiment, the end 66 of the cross wall 60″ is coupled to the side 20 of the panel 12 by folding upwardly the tab 33 defined by the slots 30A2 and 31, folding downwardly the tab 65 defined by the slot 70 ₁′ and the end 66 of the cross wall 60″, fitting together into engagement the slots 70 ₁ and 30A₂′ and then folding downwardly the tab 33 and folding upwardly the tab 65. In another alternate embodiment, the slot 31 may be omitted, and the slot 30A₂′ may be extended beyond the fold line 28A toward the fold line 26 and sized to receive the entire end 66 of the cross wall 60″ (from the bottom end 62 to the top end 64) therein. Once received in such an extended slot, the cross wall 60″ may be moved in the direction outwardly away from the upstanding side wall 32 until the slot 70 ₁′ aligns with the extended slot, and the cross wall 60″ may then be moved upwardly until the terminal end of the slot 70 ₁′ engages the terminal end of the slot 30A₂′.

In either of the foregoing embodiments, such a cross wall-to-panel coupling arrangement may be applied to any one or more of the cross walls 60 illustrated and described hereinabove to “lock” the partition structure (i.e., the one or more cross walls 60 and the one or more interior side walls 40, in embodiments which include one or more interior side walls 40) to the panel 12. As one specific example of such an arrangement, either one or a combination of the cross wall-to-panel coupling arrangements just described may be applied at each of the four corners of the multi-cell partition 80′.

As also illustrated by example in FIG. 7, once the multi-cell partition 80, 80′ is fully deployed to its open position (e.g., as illustrated in FIG. 6), one or more conventional attachment mechanisms may be affixed or applied to and between one or more of the interior side walls 40 and the panel 12, 12′, 12″ in order to affix the partition structure (i.e., the one or more cross walls 60 coupled to the one or more interior side walls 40, in embodiments which include one or more interior side walls 40) to the panel 12, 12′, 12″ at one or more points or areas of the panel 12, 12′, 12″ other than the flaps or tabs 32, 34, i.e., inwardly of the fold lines 28A, 28B, to thereby inhibit movement of the partition structure relative to the panel 12, 12′, 12″. In the illustrated embodiment, for example, a conventional attachment member 90 may be applied to and between the end 48 of the interior side wall 40 which aligns with the fold line 26 and the bottom surface 24 of the panel 12″. Such an attachment member 90 may be applied at one end or at each opposing end of the interior side wall 40, and/or may be applied at either or both opposing ends of one or more other interior side walls 40 and/or to one or more of the cross members 60, 60′ anywhere along the length thereof. Illustratively, the attachment member 90, or other configuration thereof, may be provided in the form of one or a combination of an adhesive-backed tape, a mechanical clip, staple, or the like. Those skilled in the art will recognize other conventional attachment mechanisms that may be used to affix the partition structure (i.e., the one or more cross walls 60 and the one or more interior side walls 40, in embodiments which include one or more interior side walls 40) to the panel 12, 12′, 12″, or to otherwise prevent or inhibit movement of the partition structure relative to the panel 12, 12′, 12″, after the multi-cell partition 80, 80′ is fully deployed to its open position (as illustrated in FIG. 6), and it will be understood that any such other conventional attachment mechanisms are contemplated by this disclosure.

In the embodiments illustrated and described herein, the cells formed by the exterior side walls 32, 34 and one or more cross walls 60, 60′ and, in some embodiments, also by one or more interior side walls 40, are substantially equal in their dimensions. In alternate embodiments, it will be understood that one or more cross walls 60, 60′ and/or one or more interior side walls 40 and/or the panel 12, 12′, 12″ may be configured, e.g., via suitable choice of location of one or more of the slots formed therein, to provide one or more cells having different dimensions than others of the cells.

The panel 12, 12′, 12″ and the one or more cross walls 60, 60′ (and the one or more interior side walls 40 in embodiments which include one or more interior side walls 40) may, in some embodiments be formed of single sheets of single or multi-layered fibers, e.g., paper. In some alternate embodiments, the panel 12, 12′, 12″ and the one or more cross walls 60, 60′ (and the one or more interior side walls 40 in embodiments which include one or more interior side walls 40) may be formed of multiple sheets of single or multi-layered fibers that have been formed or adhered together and/or that are separated by one or more interconnecting (e.g., corrugated or other) layers. In still other alternative embodiments, the panel 12, 12′, 12″ and the one or more cross walls 60, 60′ (and the one or more interior side walls 40 in embodiments which include one or more interior side walls 40) may be formed of single or multi-layered sheets of a suitable polymer material, e.g., a polyolefin. In any such embodiments, the fold lines 26, 28A, 28B, 72 may be formed by pre-creasing or pre-stressing the material used for the panel 12, 12′, 12″ and for the one or more cross walls 60, 60′.

In other alternate embodiments, the panel 12, 12′, 12″ and the one or more cross walls 60, 60′ (and the one or more interior side walls 40 in embodiments which include one or more interior side walls 40) may be formed of multiple polymer sheets that have been formed or adhered together and/or that are separated by one or more interconnecting (e.g., corrugated or other) layers. In any such embodiments, the fold lines 26, 28A, 28B, 72 may illustratively be formed as living hinges using conventional living hinge formation techniques. In still other alternate embodiments, the panel 12, 12′, 12″ may be formed of one or multiple polymer sheets and the one or more cross walls 60, 60′ (and the one or more interior side walls 40 in embodiments which include one or more interior side walls 40) may be formed of one or multiple fiber sheets. In further alternate embodiments, the panel 12, 12′, 12″, the one or more cross walls 60, 60′ (and the one or more interior side walls 40, in embodiments which include one or more interior side walls 40) may each be formed of any one or combination of any of the foregoing materials. Other materials and/or material combinations will occur to those skilled in the art, and any such other material(s) and/or material combinations of the panel 12, 12′, 12″ the one or more cross walls 60, 60′ and one or more interior side walls 40, in embodiments which include such one or more interior side walls 40, are contemplated by this disclosure.

It will be recognized from the foregoing that the multi-cell partition illustrated and described herein does not require the use of any adhesives or other bonding media in its construction. Rather, the various components of the multi-cell partition are coupled together strictly via mechanical attachment; more specifically, by fitting together the various components via slots formed therein. Moreover, it will be recognized that, once constructed, the multi-cell partition is readily collapsible from an open position, in which it may be used to separate multiple items for transport and/or storage of the items, to a collapsed or closed position for storage and/or transport thereof, and vice versa, without deconstructing any aspect or component thereof. Thus, as illustrated by example in FIGS. 4-6, the constructed multi-cell partition may be easily and quickly manipulated between its collapsed and open positions.

While the invention has been illustrated and described in detail in the foregoing drawings and description, the same is to be considered as illustrative and not restrictive in character, it being understood that only illustrative embodiments thereof have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected. For example, while the panel 12, 12′, 12″ is illustrated in the attached figures and has been described herein as being a planar panel, and the cross walls 60, 60′, and the one or more interior side walls 40 in embodiments which include one or more interior side walls 40, are illustrated in the attached figures and have been described herein as being generally elongated, planar walls, this disclosure contemplates alternate embodiments in which the panel 12, 12′, 12″ is not planar and/or in which the cross walls 60, 60′, and/or the one or more interior side walls 40 in embodiments which include one or more interior side walls 40, are not planar, and it will be understood that that such alternate embodiments are intended to fall within the scope of this disclosure.
